WebHostingSearch has an excellent guide to domain names; in fact, probably more than you need to know. But you'll find out about the history of DNS, the dos and don'ts in choosing a domain name, registrars, and transferring. Read the whole article here.

We'd like to interject a little though. We highly believe that choosing a brandable domain name is much more important that choosing a name with your keywords in it. A company called Lending Tree is well known and trusted, but what about Best-Loan-Offers-Online.com? Would you trust a company with a name like that? Maybe, maybe not, but it has a chincy sound to it.

Go with a brand, not a keyword.
